The Autometer Ultra‑Lite 66.7mm mechanical pressure gauge measures 0–400 PSI using a Bourdon tube movement, requiring no electrical hookup. Peripheral incandescent lighting illuminates the dial, and the gauge kit includes 1/8" nylon line, 1/8" NPT compression fittings, a 1/4" NPT adapter, bulb and socket assembly, mounting hardware and installation instructions for a complete mechanical pressure readout solution.
